Warlord Games reconfigured and remastered their Imperial Roman Testudo figure and has it available again over in their webshop.
From the announcement:
After a while out of the frontline whilst we made adjustment to the master model, our ever-popular Imperial Roman Testudo model is once again available.
The Roman Testudo (tortoise) formation is probably the most recognisable battle formation in history. We wanted to do this legendary sight on the battlefield justice and so we have included an EXCLUSIVE Centurion model leading from the front of the formation and also added a pack of metal arrows that you can stick to the shields and the base to show how effective the Testudo is in weathering a storm of missile fire.
